Cartridge Valves - Pressure Control Valves - Pressure relief

VS-30

RE18318-23-01(2023-11-22)
Description

Flow is blocked from 1 to 2 until pressure increases to meet the selected valve setting, lifting the poppet from its seat and allowing relief flow through port 2 to tank. Pressure at port 2 is additive to the relief setting of the valve. The unique Bosch Rexroth Oil Control poppet design provides enhanced stability at all flows and pressures.

¹) At 80% of pressure setting

²) Standard version 03 type

³) Only external seals for 10 valves
